'; -3 Claims. (01. 18-82) My present: invention relates a door check,

mobile doors provide 'a'door check for-a hinged door whereby vthedoormaybe readily swung about its hinges, but frictionally retainedin any desired position against easy displacementor swinging by wind,

gravity, or similar-force) Another object is to provide a very simplepositive door stop inconnection with the foregoing structure. 1

Another important object of this invention is to provide a'doo'r checkof this class which is concealed except when the door is open, and thenis not more visible than other door stops.

A further important object of this invention is to provide novel andreadily accessible means for adjusting the amount of frictionalresistance against the easy swinging or displacement of the door ineither direction.

An object also of this invention is to provide novel-means oflubricating and of retaining the 1 lubrication of the sliding rod in thegripping A further object of this inventionis to providea door check ofthis class which. is simple and economical of construction, durable, and,which will not-readily deteriorate or get out of- With these and otherobjectsin new as-will' appear hereinafter, I have devised a..door .checkhaving certain novel features of construction, as

will be hereinafter described in detail and par-,

v ticularly set forth in the appended claims, refer-- ence being had tothe accompanying drawing, and to the characters of reference thereon,which form apart. of this application, in which: Fig. 1 is asectionalview in plan, showing a 1 preferred construction of my door check, andembodiment thereof in an automobile body. and

door; I

' thereof, taken through 2-2 of Fig. 1;

Fig. 3 .is a fragmentary sectional view taken from the edge of the doorat 3-3 of Fig. 2; and, Fig. 4 is a fragmentary section thereof takenat4--4ofFig.2.-'

. In the drawing the body isidesignated I, and

1 the door 2 is mounted on .the body by'ahinge v.or hinges 3. Theabutting faces l and! of f the body and door, that is, thefaceswhich-engage each other when the door is closed, are prefer- 1 5 ablyrelieved, as in present automobileconstruc particularly adapted thoughnot limited to auto- I Fig. 2 is a fragmentary sectional elevation tion.The installation of my door check, however, is not limited totheidentical abutting faces I shown.

On the plate or member I, forming the abutting face of; the body or doorcasing, is mounted an- 5 eye member or clevis H which is preferablybolted thereto. I v

g The corresponding plate or member 2'? of the door 2 has a reinforcingplate 4. At the'inner side of this plate is positioned a slide in the 10form ofja bracket l2 which is provided. at its upper and lower ends withaligned trunnions l2 which are pivotally mounted in the bearing or eyeportions l3 of eye bolts l3, the shanks of which extend outwardlythrough the plates 4 and ll 2* and'are secured in place by nuts 13 atthe outer side of the plate 2. The centralportion of the bracket I! hasan elongated hub l2 which .has a threaded hole l2 tapered from the outerf end. A sleeve H is correspondingly threaded a at the end M and isadjustably screwed into the threaded hole l2. The threaded end islongitudinally slotted, as indicated by so that the split end iscontracted as the sleeve is screwed into the hub. The sleeve is providedwith an 25 axial bore H inwhich is slidably mounted a rod IS. The outerend of the rod I5 is pivotally connected, on a verticalaxis, to the eyemember or clevis II. On the inner end of the rod is a stop consisting ofnuts l6 and I1. Intermediate 30 the ends of the sleeve l4, andimmediately surrounding the bore, is a channel in which a packing orlubricating washer I8 is positioned'for lubricating the rod slidingtherethrough. I

The outer end 'of the sleeve is provided with 35, a transverse slot tofacilitate the adjustment of the sleeve by screwing the same into or outof the tapered threaded hole I2 As the door 2 is opened or closed, therod l5 slides through the sleeve, the pivotal mountings 4o of the outerend of the rod and of the slide or bracket l2 allowing free movement ofthe .rod laterally. The portions of the plates 2* and 4, through whichthe sleeve It extends, are horizontally elongated to permit such freemovement. I

To increase. or reduce the resistance of the sliding of the rod l5through the sleeve, the sleeve is 'adjustedinto' or out of the taperedthreaded hole.

The stop nut l6 engages the inner side of the bracket l2 when'this nutserves as stop means to limit theopening of the door.

Though I have shown and described the parti- 'cular construction, I donot wish to .be' -limited to the same, but desire. to include in thescope IQ of my invention, the construction, combination, and arrangementsubstantially as set forth in the appended claims.

I claim: I

1. In a door check, a door casing and a door hinged thereon, each havingabutting faces, a bracket within the door and pivotally mounted on theback side of its abutting face on an axis parallel to the hinged axis ofthe door, a rod pivoted at one end on the casing substantially in theplane of its abuting face, and a screw contracting sleeve on thebracket, the other end portion of the rod extending slidably andfrictionally through the axial portion of the sleeve, one end of thesleeve extending through the abutting face of the door, and having meansat said end for longitudinally adjusting the sleeve for contracting thesame.

2. In a door check, a door casing and a door hinged thereon, each havingabutting faces, a friction slide on one of the former immediately behindits abutting face, a rod pivoted at one end on the abutting face of theother of the former, and a screw contracting sleeve on the slide, theother end portion of the rod extending slidably and frictionally throughthe axial portion of the sleeve, one end of the sleeve extending throughthe abutting face of the member on which the slide is mounted, thelatter end of the sleeve having means for longitudinally adjusting thesleeve for contracting the same diametrically.

3. In a door check, a door casing and a door hinged thereon, each havingabutting faces, a bracket within one of the former and pivotally mountedon the back side of its abutting face on an axis parallel to the hingedaxis of the door, a rod pivoted at one end on the abutting face of theother of the former, and a screw contracting sleeve on the bracket, theother end portion of the rod extending slidably and frictionaliy throughthe axial portion of the sleeve, one end of the sleeve extending throughthe abutting face of the member on which the bracket is mounted, thelatter end of the sleeve having means for longitudinally adjusting thesleeve for contracting the same diametrically.
